Spectral energy distribution for the MEL best-fit solutions. Open histogram takes into account all sources, while the shaded histograms consider only the sources with good photo-z solutions. We find that none of the ALHAMBRA BLAGN/QSOs is well-represented by a stellar template. Of all the extragalactic templates considered, the majority (95.3%; 142 out of 149) of the sources with good solutions (i.e. no outliers) have best-fit templates compatible with a pure QSO or hybrid QSO/ULIRG template.
